Sanderson's eerie second fantasy (after 2005's Elantris ), set in a mist-haunted, ash-ridden world, pits Kelsier, "the Survivor of Hathsin," against the immortal Lord Ruler's 1,000-year domination of both the Great Houses and their serflike "skaa." Through Allomancy acquired in the Ruler's most hellish prison, Kelsier can "burn" 10 metals internally, fueling superhuman powers he uses to assemble rebels in a loose plan to destroy the nobility, the empire and the Lord Ruler himself. Kelsier uses Vin, a street urchin with the same Mistborn powers Kelsier possesses, to infiltrate the Great Houses' society, where she falls in love with philosopher prince Elend Venture. This mystico-metallurgical fantasy combines Vin's coming-of-age-in-magic and its well-worn theme of revolt against oppression with copious mutilations, a large-scale cast of thieves, cutthroats, conniving nobles and exotic mutants. The fast-paced action scenes temper Vin's interminable ballroom intrigues, while the characters, though not profoundly drawn, have a raw stereotypic appeal. (July)
